ANDREW 'W 0L1), OF SPOKANE, WASHINGTON.

To all whom it may concern Be it known that l, ANDREW VVOLD, citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Spools, of which the following is a specification.

The object of the present invention is to provide in a thread spool a knife located 011 one end thereof directly in front of a slot, to cut the thread by merely drawing same through the slot.

The invention consists further in the novel combination and arrangement of parts to be hereinafter fully described, and specifically pointed out in the claim, reference being had to the drawings hereto annexed, in which:

Figure 1 is a perspective view of a spool with thread cutter in position. Fig. 2 is a sectional view through the center of the spool taken on the line a-a of Fig. 1. Fig. 3 is a fragmentary view of one end of the spool showing the recess provided to receive the knife blade for cutting the thread. Fig. t is a perspective view of the blade. Fig. 5 is a perspective view of one of the downturned points at the end of the spool showing the seriated edges and the upturned point of which prevent the blade from withdrawing from the wood.

Referring to the drawings: The spool 10 is provided on one of its flanges 11 with a recess 12 pressed into the flange, of sufficientdepth to correspond with the thickness of the blade 13. On the edge of the flange at 14; is provided a slot cut at an angle to the tangent and being deep enough to enter within the area of the pressed space 12, so that when the blade is in position the cutting edge will project into the slot and when the thread is drawn through the slot it will come in contact with the cutting edge 15 of the blade 13 and be severed. The blade 13 is formed of steel or other metal suitable to provide a. cutting edge and supports on either end a down-turned pointed member 16 which enters the wood of the spool to retain the blade. On the face of the downturned member 16 are series of teeth formed into said face. lh hen the blade is cutting, these teeth act to prevent the blade from withdrawing or detaching itself from the Specification of Letters Patent.

spool. The teeth being so positioned that the points may easily enter the wood of the spool, but will grip and engage with the fiber of the wood to prevent. withdrawal. To further accomplish this purpose at a point midway of the point 16 a portion of the metal 17 is sheered to provide an upwardly pointing spur with the points thereof slightly rounded and pointing outward as the blade is driven into the wood, the point, being of a hard. and springy metal will always engage with the side of the cutformed by the point 16 and if the blade becomes loose through the shrinkage of the wood and tries to disengage itself from the spool the point will enter the wood to prevent its removal. The blade 18 is beveled at 15 to provide a cutting edge, said edge being also rounded to conform to the circle of the flange of the spool. On account of the bevel the edge is slightly recessed on the face or end of the spool so that there is no danger of cutting the hand when using the spool.

The device herein described is simple in structure, and it effectually serves the purpose for which it is designed, the thread on the spool being merely drawn into the slot and across the edge of the blade to sever it.

I claim:

In combination, a spool having a flanged head provided on its outer end or face with a flat recess disposed radially inwardly of the peripheral edge of the flange and with the bottom of the recess parallel with the outer or end face of the spool head, and a flat cutter plate closely fitting the margins of said recess and of a thickness to lie substantially flush with the outer face of the spool head, said plate having a rounded cutting beveled edge with the sharp portion of the beveled edge disposed atthe bottom of the recess, and said head having a thread slot extending from the peripheral edge of the head flange to said rounded cutting edge of the plate, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.
